If (leeirml also,strap or suspenrlii' device 8- mey be employed lo lie pinion 25 rigidwit h the While secured to the outer face ofsaid plate, preferably bymeans of rivets 10, are the ends of a segmental plate 11 provided withany desired number of holes or perforations 12 located suitabledistances from each other, see more especially Fig. Pivoted at 13 to theouter surface of the plate 5, is the rearward end of a forwardlydisposed member 14, while pivoted at 15 to the forward end of thismember is an arm 16, the rearward end of which is formed at the edgethereof with a series of teeth 17 disposed on the arc of a circle, saidteeth being adapted to be engaged by a pin 18 carried at the inner sideof the forward end of a'pawl l9 pivoted at 20 to the outer side of thesaid forwardly disposed member 14, said pin also being-of lengthsufiicient to enter any desired one of the holes 12 in the segmentalplate 11 whenever the arm 16 may be adjusted relatively to the member14, either up or down, in a manner to bring thespace between any two ofthe said teeth 17 in registry with or before said desired, one of theholes. Y

Rotatably supported by the said arm 10 in any suitable way, is a shaft21, rigid with which is a toothed gear-wheel 22 of proper size ordimensions, said shaft having also rigid therewith at its outer end anoperating crank provided at its free end with a suitable handle 2%. Theteeth of this gear-wheel engage with the teeth of a outer end of a shaft26, also rotatablysupported by the member 16 at or near the free endthereof, the said shaft 26 having rigid therewith, on the inner side ofthe member 16, a balance wheel 27, and also having connected thereto at,its inner end, in any suitable way, one endof a flexible shaft 28, thefree end-portion 29 of which is rotatablyreceived in a bearing 30therefor supported by a flange 31 of an tension 32 of the back-plate 33,rigid with which are the-stationary bladesor cutters 34: of the trimmingdevices proper for my impro ed structure.

The extremity of the said end portion 2!) I of the flexible shaft isprovided with a disk the reciprocatory member 40 of the trimming devicesproper through the intermediacy of the said pitman 38, it beingunderstood that in this way the-trimming devices proper are operated totrim a hedge.

The back-plate 40 of the trinnning devices proper has an evtension ylfl.to which is secured. by means of a pin or rivet H. the memb r t?) of abra ket. the other member 46 of which has movubly secured thereto bymeans of a screw 47 and nut 48. the forward end or extremity of atubular member 41.) which is supported in a sleeve 50 in a manner to beboth rotated and adjusted longitudinally thereim and held to eitherposition to which it may be set by means of a screwpin 51 and nut saidpin being inserted throt'igh correspoiuling openings 5?: therefor,

with which may be made to register any desired ones of correspondingopenings 53 a formed insets in the said tubular member 49, disposed outof alinement with each other at different portions of saidtubularmember.

in this way this tubular member may be located in the sleeve to carrythe trin'nning devices proper to any desired position laterally of theremaining elements of the structure, while due-to theinova-bleconnection between the forward end of the tubular meml'ier and themember 46 of the hereinbeforementioned bracket. it is apparent that thetrimming devices proper may be'tilte'd or inclined at any desired angle,either upwardly or downwardly relatively to the hedge being trimmed. andsecured in such position by simply tightening the nut 48 upon the screwlT. The sleeve 50 is mounted upon one end of a rod 54-. prc'l'emblyhaving a covering 55 of rubber or other soft or yieldable material.

stantially right angles thereto, is one end of a plate .36, carrying atthe other end thereof 7 a suitable cuff or support- 57 for the forearmof the operator. which trinnning. by which to'brace and strengthen thearm of the operator while engaged with 36 carrying a crank-pin 37, inmovable connection with which is a .pitman 38, the outer end of which isin movable connection at 39 with the reciprocatory member it) for'oscil- I lating the movable l lades or cutters 41. ot the trimmingdevices proper, each of which is pivoted at 42 relatively to the saidstationary I v w I -1 the tor 'ardly disposed plate 1.4, it is aplt\vill thus be seen the handle 24 of the .to the disk 36 and itscrank-pin, thence to turning the same to impart euii' may be sometimesemployed in the operations ot hedge t he structure'in the trimn'iing ofa hedge.

From the foregoing it will be seen that my in'rproved lledge-trimmermaybe adapted to any of the requireinei'its of such a structure, and it:should be added that instead of altering the position of theulotion-transmitting devices for the trimming devices proper byadjusting the member '16 with reference to parent. thatsimilaadjustments may be effeett-d by raising or lowering the said plate14 on its pivot 13, and securing it in the de sired position withreference to the body of the operator by means of thehereinbeforementioned pin 18, which is inserted in the proper one of theholes 12 in the segmental. plate 11.

It will be understood that the hand-grip i's manipulated with one hand,while the mo.- tlon-transmitting devices are operated with the other.

It should be added that the pawl 19 is:

(slprung' against the side'of the forwardly sposed plate 14, andt-hat'the latter has a, hole or openlng 58 therein which, in theadjustments of the plate ,,is made to, register with the appropriate.one of the holes or openings 12 in the segmental-plate. 4, it beinapparent that the pin 18 carried at the en of thepawl also extendsthrough said hole 58,;and to disengage which the pawl has to be pulledoutwardly from the plate, again springing into place when released.

It should be further added that the oscillatory blades or cutters 41 ofthe trimming (lGVlCQS; proper aren'i pivotal relation withthereciprocatory member 40, at 59, thus to be actuated therefrom in anobvious manner.
